TFKit will not see it otherwise.

Shellfu v0.10.4+ will use the newer format.  This does not justify
hard dependency change, as no known functional components rely on the
version; only thing that uses it is sfdoc to display module version in
man page footer.

No need to use package name if there is only single binary package.

Overview of changes:

 *  Added missing python dependencies
 *  Fixed Debian build time test

Turns out that dehbelper does not install the package on its own so
we have to deal with it manually.

Already v0.1.0 since it's been used for ages as part of BMO (my other
project, not released yet.)
